摘要
瞄控台自动控制器由AT98C2051、电桥和电压比较电路及数控电位器X9241组成．单片机根据电压比较电路敏感电桥两臂不平衡电压输出信号的正负极性控制X9241,实现电桥平衡和控制器的自动调节。X9241采用二线串行I2C总线与单片机传递数据。其软件由主程序、中断子程序组成。
Abstract： The control0ler of aiming control plattorm （ACP） is composea wire AT98C2051, voltage comparing circuit, electric bridge and digital potentiometer X9241. The adjustment of X9241 is controlled by SCM according to the polarity of imbalance voltage signal from the output of the circuit bridge, and the adjusting of the balance of bridge and of controller is realized automatically. Data between X9241 and SCM is transmitted with I^2C Bus, and the software includes main program and interrupt subprogram.
